3D Slicer Craniomaxillofacial Modules Support Patient-Specific Decision-Making for Personalized Healthcare in Dental Research.

The biggest challenge to improve the diagnosis and therapies of Craniomaxillofacial conditions is to translate algorithms and software developments towards the creation of holistic patient models. A complete picture of the individual patient for treatment planning and personalized healthcare requires a compilation of clinician-friendly algorithms to provide minimally invasive diagnostic techniques with multimodal image integration and analysis. We describe here the implementation of the open-source Craniomaxillofacial module of the 3D Slicer software, as well as its clinical applications.

Twenty-year clinical experience with fixed functional appliances.

Introduction: Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task.

Objective: To describe the development of fixed functional appliances as well as our 20-year experience working with them.

Methods: Fixed functional appliances are grouped into flexible, rigid and hybrid.

Effectiveness of Maxillomandibular advancement (MMA) surgery in sleep apnea treatment: Case report.

Obstructive sleep apnea (OSA) is characterized by episodes of pharyngeal collapse during sleep. Craniofacial alterations such as retrognathia are often found in OSA patients. Maxillomandibular advancement (MMA) surgeries increase the pharyngeal space and are a treatment option for OSA.

Generalized odontodysplasia in a 5-year-old patient with Hallermann-Streiff syndrome: clinical aspects, cone beam computed tomography findings, and conservative clinical approach.

This article aims to report the main clinical aspects, cone beam computed tomography (CBCT) findings, and conservative oral rehabilitation in a child born from a consanguineous marriage who presented with Hallermann-Streiff syndrome (HSS) and generalized odontodysplasia. A 5-year-old girl presented with a diagnosis of HSS for oral evaluation. Radiographically, all teeth showed wide pulp chambers and roots with thin dentinal walls and open apices, resembling ghost teeth and indicating a diagnosis of odontodysplasia.

Evaluation of the upper airway in obstructive sleep apnoea.

The evaluation of the upper airway (UA) includes the physical examination of pharyngeal structures and a number of imaging techniques that vary from the mostly used lateral cephalometry and computed tomography to more sophisticated methods such as tri-dimensional magnetic resonance image (MRI). Other complex techniques addressing UA collapsibility assessed by measurement of pharyngeal critical pressure and negative expiratory pressure however are not routinely performed. These methods provide information about anatomic abnormalities and the level of pharyngeal narrowing or collapse while the patient is awake or asleep.

Cephalometric characteristics and dentofacial abnormalities of pycnodysostosis: report of four cases from Brazil.

Pycnodysostosis (PKND) is a human autosomal recessive genetic disorder characterized mainly by osteosclerosis of the skeleton, severe bone fragility, and short stature. This syndrome usually presents very typical craniofacial deformities, such as beaked nose, micrognathia, hypoplastic midface, open mouth posture, grooved palate, anterior cross-bite, dental crowding, and over-retained deciduous teeth. Early diagnosis and intervention are of the utmost importance.
